NTTEE STATES PATENT OFFICE.

All/IOS WOEBER AND JOHN LAMMERS, OF CINCINNATI, OHIO, ASSIGNORS OFONE-THIRD TO HENRY LAMMERT, OF SAME PLACE.

WINDOW-FRAME.

SPECIFICATION forming part of Letters' Patent No. 379,920, dated March20, 1888.

Application filed April 15, 1887.

To all whom it may concern.-

Be it known that we, AMos WoEEER and JOHN LAMMERs, of Cincinnati, in thecounty of Hamilton and State of Ohio, have invented a new and usefulImprovement in Window- Frames, which improvement is fully set forth inthe following specification and accompanying drawings, in which- Figurel is a top sectional view of our irnproved window frame and sash, andFig. 2 is a perspective view of a section of the frame and sash.

The object of our invention is to construct a window sash and framewhich areso arranged i5 that the sash can be hinged so as to open andclose like a door, while at the same time weights can be used, as withthe ordinary frame and sash; and it consists of a frame having thedividing-strips between the sash made T-shaped, and in providing theinner and outer hol ding-strips with tongues, which project into groovesin square sliding bars, which are of the same height as the sash, andwhich bars t in the spaces usually occupied by the sash. 'To these barsthe sashes are hinged, and as the weight-ropes are attached to thesesliding bars there will be no interference in sliding the sash up ordown, all of which will now be fully set forth in detail.

In the accompanying drawings, A represents the hanging stile of a boxwindow-frame, and B the rear stile. These are constructed, preferably,as shown, by being made the same width as the thickness of the twosashes and the intervening sash-strip. The weight-chambers are formed bya dividingstrip, C, gained in the two stiles A B. The inner side of theweight-box is formed by a board, D, the edge D of which extends slightlypast the face of the hanging stile A, so as to form one side of theguideway for the sash-bar. The finishing casing E is then placed on thebox-piece D. The other side of the box-chamber is formed by a board oreasing, F, one edge of which projects a considerable distance over theface of the hanging stile, so as to cover the joint between the slidingsash-bar and sash, as will be hereinafter shown. The outer or finishingcasing, G, is then placed on the box-piece F. 5o This form ofconstructing the boX-frame is Serial No. 234,921. (No model.)

adapted to wooden houses; but for stone or brick houses the outercasing, G, is not employed, and we change the construction of thehanging stile by makingit wider, or so as to project out, the same as inbox-frames now made.

The projecting edge Dl of the inner side, D, of the weight-box has amoldingstrp, H, secured thereon, which projects inwardly past the innersurface ofthe piece D. The outer piece, F, has also on its projectingedge F a 6o tongue, I, and midway between the box-castings D F is aT-strip, J, secured to the face of the hanging stile A by means of agroove.

K K are sliding sash-bars, the former of which is for the upper sash andthe latter for the lower sash. The bars K are preferably square incross-section, and are as long as the height of the sash, and of thesame thickness and width. These bars have grooves L on opposite sides,in which the tongues I J operate. 7o i There is also a groove next thehanging stile,

in which the weight-rope N lies. The upper sash, O, is hinged to one ofthe sliding barsK on the inside. The bars K are made the same asthe barsK in crosssection, except that a rabbet is formed along the side nextthe sash O', and the sash itself has a corresponding rabbet,

so as to make a tight joint when the sash is closed.

The weight-cords, being attached to the sash- 8o bars K` K', operate thesame as though connected directly with the sash.

Inorder to lock the sash to the bars K K on the side opposite to thehinges, a pin, Y, or other suitable means, may be employed. It is 8 5also obvious that the bars K Kl can be ioeked at any point by the use ofpins Y', or by any other locking mechanism. The pin Y would of course beused Whenever it should become necessary to open the sash on theirhinges, so 9o as to prevent the weights from drawing up the bar. In suchcases the entire weight of the sash would rest on the opposite bar, andthere would be no danger of the single weight on that side raising thesash.

It will be observed that the bars on opposite sides are not connectedwith each other except through the medium of the sash.

We further call attention to the fact that the meeting-rails of the sashcan be made the same Ico in this as in the ordinary sash, so as to ll upthe interstice formed bythe strip between the two sashes.

5 In a sash-frame, the hanging stile A, the rear Stile, B, thedividing-strip C, the pieces D and F, extending beyond the hangingstile, the latter having the tongue I, the sash-bars K and K', groovedon opposite sides, and the tongue 1c J between said bars and tting inits inside grooves and the molding H, and the sashes hinged to saidbars, substantially as described. In testimony that we claim theforegoing we have hereunto set our hands, this 8th day of April, 1887,in the presence of Witnesses.
